A native Mail, Calendar, People, and To Do client for Windows.
Microsoft Store · Release notes · Contributing
I'm a big fan of Windows Mail & Calendars due to its simplicity. Personally, I find it more intuitive for daily use cases compared to Outlook desktop and the new WebView2 powered Outlook version. Seeing Microsoft deprecating it dragged me into starting to work on Wino a couple of years ago. Wino's main motivation is to bring all the existing functionality from Mail & Calendars over time without changing the user experience that millions have loved since the Windows 8 days in Mail & Calendars.
Wino started before the current AI era. The project welcomes AI-assisted contributions when they comply with its coding rules, architecture, and maintainer decisions.
Install Wino Mail from the Microsoft Store or directly with App Installer.

GitHub Releases lists every stable version available in Microsoft Store, with its full list of changes and fixed issues.
The beta channel gets new changes before they reach Microsoft Store. Beta builds can contain unfinished changes and are for testing. Install the beta with App Installer; it installs next to the Store version.
